Morbi or Morvi is a city known as a ceramics capital of India is in the
Morbi district in the state of Gujarat, India. It is situated on the Kathiawar
peninsula. In 2011, the city's population was determined to be 194,947.[2]
The city is on the Machhu River, 35 km (22 mi) from the sea and 60 km
(37 mi) from Rajkot.

On 30 October 2022, five days after reopening, the bridge collapsed at 6:40 p.m. More
than five hundred people were on the bridge at the time of the collapse, far exceeding the
official capacity of 125. Security footage of the bridge showed the structure shaking
violently and people holding onto cables and fencing on either side of the bridge before
the walkway gave way. Images of rescue and recovery operations showed the walkway had
divided at its midpoint, with some pieces still hanging from snapped cables.

A survivor said that so many people on the bridge could barely move and that pieces of the bridge
crushed some victims. Mohan Kundariya, a Member of Parliament, Lok Sabha who lost twelve
family members including his sister in the incident, said he believed the cause was overloading. A
spokesperson for Oreva said that it appeared too many people were in the middle section of the
bridge "trying to sway it".

Detail information

The failure was caused by excessive rain and massive flooding
leading to the disintegration of the earthen walls of the four
kilometre long Machchhu-2 dam. The actual observed flow
following the intense rainfall reached 16,307 m3/s, thrice what
the dam was designed for, resulting in its collapse. 762 metres
(2,500 ft) of the left and 365 metres (1,198 ft) of the right
embankment of the dam collapsed.[7] Within 20 minutes the
floods of 12 to 30 ft (3.7 to 9.1 m) height inundated the low-
lying areas of Morbi industrial town located 5 km below the
dam.[6]

VICTIMS:-At least 135 people were confirmed dead, and more than 180 were rescued.
A large number of the victims were women, the elderly,[19] and children (39 boys
and 16 girls) with the youngest fatality being an 18-month-old baby. The government
of Gujarat announced an ex gratia payment of ₹4 lakh (US$5,000) to the next of kin
of each person who died, and ₹50,000 (US$630) to the injured.
INVESTIGATION:-Initial reports said that the bridge was reopened early after repairs,
without the required certificate of fitness from the local civic authorities. The chief
officer of the municipality, who had agreed on the contract for repairs after the 2001
earthquake, said the private firm responsible for the renovations "threw the bridge
open to visitors without notifying us, and therefore, we couldn't get a safety audit of
the bridge conducted".
10. MORBI DAM DISASTER
INTRODUCTION:

FoDS – Civil Engineering Department
:
The first dam on the Machchhu river, named Machchhu I, was built in 1959, having
a catchment area of 730 square kilometres (280 sq mi). The Machchhu II dam was
constructed downstream of Machchhu I in 1972, and has a catchment area of 1,929 square
kilometres (745 sq mi).[5]
It was an earthfill dam. The dam was meant to serve an irrigation scheme. Considering the
long history of drought in Saurashtra region, the primary consideration at the time of design
was water supply, not flood control. It consisted of a masonry spillway of 206 metres (676 ft)
consisting 18 sluice gates across the river section and long earthen embankments on both
sides. The spillway capacity provided for 5,663 cubic metres per second
(200,000 cu ft/s).[6] The embankments were of 2,345 metres (7,694 ft) and 1,399 metres
(4,590 ft) of length on left and right side respectively.[7] The embankments had a 6.1 m top
width, with upstream and downstream slopes 1:3 (V:H) and 1:2 respectively; and a clay core
extending through alluvium to bedrock. The upstream face consisted of 61 cm small gravel
and a 61 cm hand packed rip-rap. The dam stood 22.6 metres (74 ft) above the river bed and
its overflow section was 164.5 metres (540 ft) long. The reservoir had a storage capacity of
101,020 cubic decametres (81,900 acre-feet).[8]

Around 3.30 pm the tremendous swirling flow of water struck Morbi. Water level rose to 30
feet (9.1 m) within the next 15 minutes and some low lying areas of city were under 20 feet
(6.1 m) of water for the next 6 hours.[2]
The Morbi dam failure was listed as the worst dam burst in the Guinness Book of
Records[9] (before the death toll of the 1975 Banqiao Dam failure was declassified in
2005).[10] The book No One Had A Tongue To Speak by Tom Wooten and Utpal Sandesara
debunks the official claims that the dam failure was an act of God and points to structural and
communication failures that led to and exacerbated the disaster.[11] There was great
economic loss. The flood damaged farmland, leading to a decrease in productivity of crops.

13. “WHAT IS BHOPAL GAS TRAGEDY ?”
The Bhopal gas tragedy (commonly referred to as Bhopal disaster) was a
gas leak inciden...y
The Bhopal disaster or Bhopal gas tragedy was a chemical accident on the night of 2–3
December 1 984 at the Union Carbide India Limited (UCIL) pesticide plant in Bhopal, Madhya
Pradesh, India. Considered the world's worst industrial disaster,[1] over 500,000 people in the
small towns around the plant were exposed to the highly toxic gas methyl isocyanate (MIC).[2]
Estimates vary on the death toll, with the official number of immediate deaths being 2,259. In
2008, the Government of Madhya Pradesh paid compensation to the family members of 3,787
victims killed in the gas release, and to 574,366 injured victims.[3]A government affidavit in
2006 stated that the leak caused 558,125 injuries, including 38,478 temporary partial injuries
and approximately 3,900 severely and permanently disabling injuries.[4]Others estimate that
8,000 died within two weeks, and another 8,000 or more have since died from gas-related
diseases.[5]

The owner of the factory, UCIL, was majority owned by the
Union Carbide Corporation (UCC) of the United States, with
Indian government-controlled banks and the Indian public
holding a 49.1 percent stake. In 1989, UCC paid $470 million
(equivalent to $907 million in 2021) to settle litigation
stemming from the disaster. In 1994, UCC sold its stake in
UCIL to Eveready Industries India Limited (EIIL), which
subsequently merged with McLeod Russel (India) Ltd.
Eveready ended clean-up on the site in 1998, when it
terminated its 99-year lease and turned over control of the
site to the state government of Madhya Pradesh. Dow
Chemical Company purchased UCC in 2001, seventeen years
after the disaster.

TECHNILOGICAL DESASTER
Technical disaster is an event or series of events that
results in the destruction or disruption of technology-based
systems and services, potentially leading to significant data loss
and economic damage. This can include the failure of hardware,
software, networks, or other components of a technology
infrastructure. It can also involve the unauthorized access and
destruction of data or services.
23.
24. Cyber attack
Cyber attacks are malicious activities that aim to damage or
disrupt computer networks, systems, and services. Cyber attacks
can take the form of viruses, malware, ransomware, phishing,
and other malicious software or activities. Cyber attacks can be
used to steal data, spread malware, disrupt services, and cause
financial harm. Cyber attacks can also be used to target critical
infrastructure and disrupt operations. Cyber attacks can be
launched by individuals, groups, or governments, and can be
targeted at any organization or individual.
26. HACKING
This type of attack involves unauthorized access to
confidential data, such as financial information, customer
records, and intellectual property. Hackers use various
techniques, such as phishing, malware, and social engineering,
to gain access to sensitive information. The goal of this type of
attack is typically to steal data for financial gain, to damage the
victim's reputation, or to disrupt operations.
27. ETHICAL HACKAL
Ethical hacking is the practice of testing a computer
system, network, or web application to find security vulnerabilities that an
attacker could exploit. Ethical hackers use the same knowledge and tools as a
malicious hacker, but instead of taking advantage of the discovered
vulnerabilities, they report them to the organization so that they can be fixed.
28. GREY HAT HAKER
The term "gray hat hacker" is used to describe a computer
security expert who sometimes works with the law and sometimes
works outside of it.
29. BLACK HAT HAKER
A black hat hacker is an individual who attempts to gain
unauthorized access to computer systems or networks with
malicious intent. These hackers are often motivated by financial
gain, though they may also be motivated by a desire to disrupt or
damage systems and networks.

Summary
A Technological disaster is an event
caused by a malunction of a
technological structure and/some
human error in controling and handling
the technology.
